Cyrus PSX-R Power Supply

The Cyrus PSX-R is a separate power supply that may be added to most Cyrus components to further improve performance. It’s connected to the mains and acts like a giant battery. The Cyrus PSX-R feeds the highly tuned audiophile circuitry in your CD or amp with super smooth ‘regulated’ DC power to allow the advanced circuitry to perform without the ‘noise’ that is present in the public mains supply. We describe a Cyrus PSX-R as a resolution enhancing upgrade. A system could include a number of Cyrus PSX-Rs for several components.

The intelligence built into Cyrus component means that the Cyrus PSX-R is simply plug and play. Simply plug in the umbilical lead and the linked component automatically detects the Cyrus PSX-R's presence and adjusts the way if operates accordingly.

It is a widely accepted fact in the high quality audio circles that the power supply design accounts for a large portion of the overall perceived quality of the hi-fi system. The Cyrus PSX-R is a 300W fully regulated DC Power supply designed to enhance the performance of the partnering Cyrus products when used as an optional extra. With its intelligent connectivity, the Cyrus PSX-R automatically adjusts its output parameters to suit the partnering Cyrus component.

• A 300VA toroidal transformer with an enormous current delivery capability forms the front end of the Cyrus PSX-R. The 30,000 microfarad slotted foil reservoir capacitors ensure that very low ESR and wide bandwidth are presented to the linear mode regulator stage that follows.

• The symmetry as a design objective set out in the Cyrus range continues to be an important topology feature of this wide dual bandwidth DC amplifier working as a linear voltage regulator in an identical manner for the positive and negative sides of the Cyrus PSX-R.

• Current sharing fast double output power transistors ensure quick response in providing the demanded current from the partnering Cyrus unit. Low noise high gain amplifiers in a propriety design provide the remarkable load and line regulation afforded by the Cyrus PSX-R.

• The intelligent nature of the control circuitry built into the Cyrus PSX-R not only sense the requirement of the partnering Cyrus component but also relinquish the power-on control to that unit to allow ergonomic operation of the system. At the same time this elegant circuit protects against mal-operation of the Cyrus PSX-R beyond the designed parameters.

• Connection to the partnering Cyrus unit is made through a quality XLR cable assembly that ensures tight coupling and minimal loss in efficient and fast energy transfer. In all instances except for high current applications the Cyrus PSX-R may be added into the system without any changes to the existing components and by merely plugging the unit in.

• In low Power applications such as CD or DVD players the addition of the Cyrus PSX-R provides a highly stable external Power with massive inertia which ensures ideal battery like operation for such units. In high Power applications, on the other hand, the Cyrus PSX-R while establishing a very stiff voltage source behind the power amplifier, it successfully inhibits mains related distortions and charging spikes from reaching the signal lines of the amplifier.

• The quality lightweight die-cast enclosure of Cyrus PSX-R has a myriad of advantages both electrically and mechanically. The integrated heatsink design enhances the thermal efficiency allowing higher performance to size ratio. Additionally, the non-resonant nature of the alloy minimises microphonic effects, while its non-ferrous composition provides an effective shield from external electro-magnetic disturbances. This also eliminates coupling of the power transformer stray magnetic fields to the sensitive audio circuitry.
